How to subtract hexadecimal number when one is bigger than the other?

Inessa05 [86]

Hello,

In order to be simple: let's code hexadecimal numbers on 4 digits.

Example: 500-200=300 (in décimal)

$500_{10}=01F4_{16}\\\\
200_{10}=00C8_{16}\\\\
For\ subtract\ 00C8\ we\ calculate\ 15th\ complement\\\\
C_{15}(00C8)=FF37\\\\

16th\ complement= FF37+0001=FF38\\\\

Then\ we\ add\\\\

01F4+FF38=(1)012C\ on\4\ digits:\ 012C\\

012C_{16}=300_{16}

Jamar to the local snack shop near his school He bought 3 hotdogs and 2 bags of chips for $Kenny went to the same snack shop and

lilavasa [31]

Answer:

Marcy paid $4.15

Step-by-step explanation:

Given

Represent hotdogs with x and chips with y.

So, we have:

Jamal

$3x + 2y = 4.85$

Kenny

$5x + 6y = 9.55$

See attachment for complete question

Required

Determine the amount for 2x and 3y

From Jamal's and Kenny's orders we have:

$3x + 2y = 4.85$ --- (1)

$5x + 6y = 9.55$ --- (2)

Multiply (1) by 3

$3 * [3x + 2y = 4.85]$

$9x + 6y = 14.55$ --- (3)

Subtract (2) and (3)

$9x - 5x + 6y - 6y = 14.55 - 9.55$

$9x - 5x = 5$

$4x = 5$

Solve for x

$x = \frac{5}{4}$

$x = 1.25$

Substitute $x = 1.25$ in $3x + 2y = 4.85$

$3 * 1.25 + 2y = 4.85$

$3.75 + 2y = 4.85$

Solve for y

$y = \frac{4.85 - 3.75}{2}$

$y = \frac{1.10}{2}$

$y = 0.55$

So, the cost of 2x and 3y is:

$Cost = 2x + 3y$

$Cost = 2*1.25 + 3*0.55$

$Cost = \$4.15$

Use the distance formula to find the perimeter. Round to the nearest tenth

xenn [34]

Answer:

18.8

Step-by-step explanation:

You just add the two lengths and then do pythagorean theory to get the length of the hypotenuse. Then you add them all together to get 18.8. Hope this helps.
